Abstract

The present invention relates to a qudits in two way deterministic quantum key distribution wherein it involved a two way transmission where qubits are sent to and from between communicating parties while information is encoded by unitary transformers on the qubits. A protocol sees U1 sending to U2 a state that U1 prepared and wherein U2 would then encode the said received protocol with unitary transformation. U2 would then thereafter send the encoded state back to U1 who would then measure or decode the sent state deterministically. In order to ensure the security of the protocol, a control mode used and is randomly done with a certain probability wherein instead of encoding. U2 would do a projective measurements on the qudit received whilst U1 measures the qudit sent by U2.
